Fully welded ball valve
Free-valve's fully welded ball valve are widely used in almost all the industry .Compared to the general casting ball valve, fully welded ball valve have a highly performance and longer life time . It was widely used in city gas , city heat supply , oil chemical industry, ship building , steel , power plant etc . Fully welded ball valve can be reliable run in the long time , easy to be installed and less maintenance work .
Benefits
1.Valve body material is the same as the pipe material , so they will not occur transformation due to unbalanced stress .
2.Face to face dimensions can be made according to customer requirement.
3.Material of valve seat is made up of ptfe+20%c sealing ring and metal sealing , which can adapt to the change of pressure and temperature, so the leakage will not occur during the pressure and temperature range.
4.The ball body has a highly machining precision due to the tracking of computer detector, so the ball valve was shut off/shut on conveniently.

The valve is made up of all welded body and PTFE gasket, can run long life under the condition of frequent operation¡¡éimpurities and chemicals.
Fine grinding stainless steel sphere can guarantee for years to open and close freely and reliable operation.
The structure of floating ball,.The elastic washer in the slope can guarantee for the sealing ring compression on the sphere,the valve can guarantee closely even though in the case of pressure is not stable.
Containment spindle is made up of two o-ring seals,The top of small diameter of the valve can be changed.
Both can be replaced of DN65--DN300.
THE PTFE thrust washer is between the stem shoulder and stem chamber,it also can play the role of sealing.
The stem chamber of the ball valve that more than DN65 equipped with stainless steel bearing.
Features:
Don't need maintenance, adjustments and lubrication,Easy to install,Long-term reliable operation in the Low operating cost.
The valve stem can be longer, easy to heat preservation.
Operating handle can be removed, reversing the installation.
The body does not contain heavy and unreliable castings.
It is very convenient of the install mediation organization.
The curve of the pressure/temperature (Not suitable for steam)

Ball valve open-close part for sphere, through a sphere around the body center for rotation to achieve open, closing a valve.Used for intercepting and change the flow distribution ratio or quick opening and closing.
Its characteristic is wear-resisting, good sealing, light switch, long service life.Widely used in petroleum, chemical industry, power generation, paper making, aerospace and other fields.
The advantages of the ball valve:
1, with the bottom flow resistance
2, realize completely sealed reaction in the high pressure and temperature range
3, can achieve rapid opening and closing and no impact to operation
4, not easy to get stuck at work, so reliably used in corrosive medium and low boiling point
5, double sealed more reliable
6, when the ball valve is fully open and close, sealing surface and the dielectric isolation, so the high speed won't bleed air seal face erosion by the media.
7, compact structure, light weight, can be thought of as the most ideal valve ball valve is used for low temperature medium.
8, all welded body ball valve, can be directly buried underground make internal valve from erosion, the highest service life can be up to 30 years.
Our advantage:
The company on the basis of combined with the structural advantages of ball valve, ball valve leakage protection aspects focus on improvement, the first is to use three free maintenance o-rings, adding self-styled mat, stainless steel valve stem to prevent rust and on both sides of a sphere with butterfly spring, easy to cause the medium leaking key protection area.And the company can according to customer demand, customized.
The company in the valve design and manufacturing of 32 national patents, ISO9001:2000 secondary quality system certification and CE, ANSI, UN and other international certification.Is the present domestic most professional heating valve manufacturing enterprise.
